Switzerland is famous for banking excellence—but that reputation doesn’t extend to their mobile apps and customer service. We analyzed Trustpilot reviews from thousands of Swiss banking customers to find the banks that consistently disappoint. Here are the 5 worst Swiss banking apps heading into 2026.
🔴 The Numbers Don’t Lie
- 8+ major banks with Trustpilot ratings below 2.6/5
- 2,000+ reviews analyzed across all banks
- PostFinance alone: 1,044 reviews, 89% are 1-star
- Common themes: Broken apps, useless support, account freezes
#1: Valiant Bank — 1.3/5 ⭐ (The Undisputed Champion)
78 reviews | 85% are 1-star
Valiant Bank holds the dubious honor of being Switzerland’s worst-rated bank on Trustpilot. With an astonishing 85% of reviews being 1-star, this isn’t a few unhappy customers—it’s a pattern.
💬 Customer Quote: “Needed help with my online banking (password wasn’t working) and when I called the hotline, the person asked me 10 security questions. TEN! The tenth one I wasn’t too sure about so he told me he couldn’t help me.”
Why They’re #1 Worst:
- Support is “completely useless” according to multiple reviewers
- Excessive security questions that block legitimate customers
- Customers closing accounts after just 2-3 support interactions
- Only 6% of reviews are positive
#2: Zürcher Kantonalbank (ZKB) — 2.0/5 ⭐
127 reviews | 76% are 1-star
Switzerland’s largest cantonal bank has the most reviews—and most of them are terrible. As the #4 bank in Switzerland by assets, their poor digital experience affects millions of customers.
💬 Customer Quote: “Technically they are far behind… their internet banking can’t even save the language settings.”
Why They Made The List:
- “If you have a problem, do not call them—you will spend a lot of time on the phone”
- One customer reported “huge financial loss ZKB caused me, plus 60 days and 40 emails time wasted”
- Branch staff “too busy” to help with basic account tasks
- App can’t display investment performance when you have cash in Frankly

#3: Berner Kantonalbank (BEKB) — 2.1/5 ⭐
35 reviews | 66% are 1-star
Canton Bern’s main bank has a severe trust problem. Two-thirds of reviewers gave them the lowest possible rating.
💬 Customer Quote: “Stealing money playing with interest rates. True bullshit what they write about prompt adjustment of variable interest rates.”
Why They Made The List:
- Mobile app crashes repeatedly—users report closing and reopening 10+ times
- Interest rate practices described as deceptive
- Persistent login errors lasting months
- “No one knowing what’s wrong” when customers call for help

#4: Raiffeisen Schweiz — 2.2/5 ⭐
131 reviews | 65% are 1-star
As Switzerland’s third-largest banking group with 3.7 million customers, Raiffeisen’s problems affect more people than almost any other bank on this list.
💬 Customer Quote: “Extremely poor customer service. The employees are a bunch of lazy bureaucrats.”
Why They Made The List:
- Wait times exceeding one hour for basic transactions
- Cards retained by ATMs with no recovery options—even during business hours
- “24-hour emergency line” closes after 1pm on Saturday
- Online banking “hard to use” with authentication delays up to 3 days
- Accounts closed with minimal explanation
#5: Basler Kantonalbank (BKB) — 2.6/5 ⭐
13 reviews | 85% are 1-star
Basel’s main bank has a small sample size but an extremely high 1-star rate. Their disastrous Easter 2023 e-banking migration is still causing problems.
💬 Customer Quote: “This is by far the most backward and inefficient bank I’ve ever had the displeasure of dealing with. It is stuck in the 1990s and has awful digital banking and payment systems.”
Why They Made The List:
- Easter 2023 migration left customers locked out for 10+ days
- QR code activation process “in the year 2024” frustrates users
- 90+ minute support queue wait times
- Digital banking described as “stuck in the 1990s”

BCV (Banque Cantonale Vaudoise): 1.4/5 ⭐ (51 reviews – 74% are 1-star)
Switzerland’s 3rd largest bank! Customers report mortgage denials after verbal approval, deposits going missing, and support that takes weeks to respond.
Bank Cler: 1.5/5 ⭐ (216 reviews – 81% are 1-star)
Basel retail bank (owned by BKB). Chronic login failures, unreachable phone support, and unexplained transaction blocks. Customers report being locked out of their own money.

Methodology
This ranking is based on Trustpilot reviews as of December 2026. We analyzed:
- Overall star rating (weighted most heavily)
- Percentage of 1-star reviews
- Total review count (minimum 10 required)
- Recurring complaint themes
- Recency of issues (are problems ongoing?)
Banks with fewer than 10 Trustpilot reviews were excluded due to insufficient data.

Frequently Asked Questions
Which Swiss bank has the worst app?
Valiant Bank has the worst-rated app with just 1.3/5 stars on Trustpilot. 85% of their reviews are 1-star, with customers complaining about useless support and excessive security questions that block legitimate users.
Why are Swiss banking apps so bad?
Many Swiss banks rely on legacy systems built decades ago. Combined with strict Swiss security requirements (PhotoTAN, mosaic codes, etc.) that add friction, and limited investment in user experience, the result is apps that frustrate customers.
Is ZKB a good bank?
ZKB (Zürcher Kantonalbank) has a 2.0/5 Trustpilot rating with 76% 1-star reviews. While it’s one of Switzerland’s largest banks with a government guarantee, customers consistently complain about technical issues, poor support, and outdated systems.
How do I complain about a Swiss bank?
First complain directly to the bank. If unresolved, contact the Swiss Banking Ombudsman (bankingombudsman.ch) for free mediation. For serious issues, file a complaint with FINMA, Switzerland’s financial regulator.
Are digital banks better than traditional Swiss banks?
Digital banks like Neon, Yuh, and Revolut often rate higher for basic banking and user experience. However, they may lack the full service range and government guarantees of cantonal banks. Consider your needs carefully.
What happened with BKB’s Easter 2023 migration?
Basler Kantonalbank’s e-banking migration over Easter 2023 left many customers locked out of their accounts for 10+ days. The bank later admitted a bug caused re-registration requirements when customers logged out.
Why does Raiffeisen have bad reviews despite being Switzerland’s 3rd largest bank?
Raiffeisen’s decentralized structure (220+ independent cooperatives) leads to inconsistent service quality. Customers report hour-long waits, cards stuck in ATMs, and support lines that close early despite advertising 24-hour service.
Should I switch banks if my app keeps crashing?
If problems persist after trying standard fixes (update app, clear cache, reinstall), and customer support can’t help, switching may be your best option. Document all issues first and file complaints with the Ombudsman to create a record.
